Secure-Boot for Automotive ECUs



Automotive ECUs run software that control a variety of different processes and features throughout the vehicle. Easily attacked by hackers, compromised ECUs can have a severe impact on vehicle operational safety. Arilou Secure-Boot safeguards the boot-chain, ensuring that only original, authenticated, firmware is loaded.
